Jun 26, 2018Yes, gone are the days of engine break ins, special motor oil, and the need to change gear oil at the end of the break in period. To this day all manufacturers still find it necessary to carry the same 500-1000 mile warning. It could be valid or it could be outdated, I don't know. All I know is if I just spent a pretty penny on a brand new truck, I'm not going to explicitly do the opposite of what the manual says and risk damage to my truck.
